The Hog Cholera. — We learn, says the Louisville Courier, that this fatal disease continues to prevail to an alarming extent along the Kentucky River, and the Ohio as far up as Portsmouth. At a distillery in Gallatin county, no less than 100 hogs died in two pens, in less than a week. At the Carrollton distillery the deaths among the hogs are fearfully on the increase, and we bear that the same fatality prevails in Mason county. The owners of these hogs, in most cases “try” them up into what is termed grease, which is sold to the stearine candle makers at about nine cents per pound. This is bringing the hogs readily to light[!], if it does not enlighten the world us to the cause of the disease.
